Intrinsically Safe Encoder Transducer type PEI
The intrinsically safe encoder transducer type PEI is designed to energise intrinsically safe incremental encoders and separate the signal from the encoder. The intrinsically safe encoder transducer type PEI is an intrinsically safe device with protection rating of ia, providing galvanic separation between the intrinsically safe encoder and the non-intrinsically safe power and decoding part.
PEI consists of:
- supply system with a high-frequency converter for galvanic separation (4kV) and diode barrier to achieve the protection level of ia,
- three transmission channels with galvanic separation between intrinsically safe and non-intrinsically safe parts.
Characteristics
- energises incremental encoders with intrinsically safe voltage,
- separation of signals from the encoder,
- can be used as an intrinsically safe power supply and a signal separator.
